iTunes importing screwing up

I'm ripping all my CDs back onto my HD, but have ran into a problem on a couple CDs. The final song like like 6 minutes long, when it actually only lasts about 3. And then there's this "Bonus Track" for like 20 minutes which I can't double click to play, and I know it doesn't exist anyhow.

The problem is when I import, the entire CD does just fine, but then I get to the final song and I end up with minutes of static on the end.

I'm running iTunes 3 in 10.2, if that makes a difference. Anyway got suggestions? It only happens on some CDs, not all of them. But I have ripped them all using iTunes before without problems.
